Application filed January 3, 1910. Serial No. 536,085.

To @ZZ whom it may concern' Be it known tha-t l, JOHN C. BARBER, a citizen of the United States, residing at Chicago, in the county of ,Cook and Starte of Iliinois, have invented certain new ond useful improvements in Roller-Bearings; and I do hereby declare the following to be o; full, clear, and exact description of the in-. yention, such as will enable others skilled in the art to which it appertains to make and use the some.

My invention has for its object to provide an improved roller bearing, and particularly has for its object to provide on ,improved roller side bearinp,r for cor trucks of the type 'disclosed and claimed in my pending application, S" ll. 532,531, filed of dote Dccenr ber 11th, i909.

To the above ends, the. invention consists ot' the novel devices and combinations of devices hereinafter described and defined in the claim.

,Tn the accompanying d 'awing's, which illustrate the invention, like characters indicate lile parte throughout the several views.

Referring to the drawings, Figure l is a plan view-ot the improved roller bearing' with the upper roller-engaging plate or member removed from working position; Fig, El is s vertical section taken through the conter bearing on the line alg of l; Fig. is o longitudinal section teiten through the center bearing on the line m3 w3 of'Fig. l; Iflis a. transverse vertical section taken through a portion of the center bearing on the vline nl m* of Fig, l, the roller being left in full; and Fig. 5 is a fragmentary View in section on the line i125 ot' el, the roller thereinshown being in fnll` The numerals l and 2 indicate respectively the ripper and lower bea-ring plates between which bearing rollers $3 are interposed. ln the perticular application of this roller bea 1'-- ing, shown in my said prior application, the

lower bearing plate 2 is an lnteri'nediate or .floating bearing plate, and the upper bearing' plate l is connected to and movable Awith the truck bolster, which, in turn, ispivotally connected to the car or body holster with freedom for both oscillatory or radial movei'nents `and for endwise movements trans-v versely of the truck. So for :is the present .invention is concerned, however, these upper and lower bearin@ platal may take various forms, but .in tie application of this center bearing to ear trucks, the rollers 3 should be radially disposed in respect to the intermediate pivotal connection between the truck and car holsters.

To secure the bestresults under all circumstances, and especially in car construction Where the rollers :re radially disposed, the said rollers are arranged in two concentric series. These two sets of rollers are held properly spaced and properly positioned between the upper and lower bearing plates by a so-eolled roller spacing coge, .inode up of two flat plates l placed lace to face and, shown, secured at their four corners by rivets 5. Both the upper and lower plates el have openings, in lwhich the rollers aro seated, and at the longitudinal edges ot these openings, the said Mplates are provided with upwardly and downwardly 'extended segmental rollr-retoining flanges (l. The roller-retaining flanges 6 terminate :it their edges at sach points that they do not engage either with the upper or lower bearing plates but, nevertheless, loosely hold the rollers linterloched to the cage plates properly spaced apart and free for rotation and 'under frictiona-l engagement ol the upper and lower bearing plates therewith and of the movement of one of said bearing plates in respect to the other. l

To maintain the rollers always in proper relative positions in respect to the bearing' plates, a toothed wheelor pinion 'l is journaled to the roller cagegand has el'igagement with the upper and lqwcr segmental rows ot' ,gear teeth 8 formed on the upper and lower surfaces ol' the bearing' plates .L and 2. 'lo secure the bestresults, this pinion 7 is .located at the center ot the roller canje bctwecn the two concentric serios olf rollers, and it is provided with projecting truunions that arc loosely journalod in seats forn'led in part in each ot' the two plates 4l, the ,said two plates being out away at l) to clear the said pinion.

As is evident, when the two bearing plates l and 9. areoscillated in respectv to each other, the pinion 7 will prevent slipping oi" the rollers in respect to the ,said bearing plates and 'will thus prevent the rollers from working in one direct-ion or the other beyond their proper predetermined .rorking positions :in respect to the seid bearing` plates. The coge and the cooperating pinions and teeth on the hearing plates act as a lili [We rows und having half :slats at LiL can tra?. gortioxlfs .t\\'een the smid two rmf's o45 the mmning Haufe, ifolleys arranged in, two rows and held for rounton by the Said. retaining Hang S7 :md a pinion having pro-A Suid yn
